Set the default minimum font size webkit pref to 12 for Chinese and 10 for ja,ko,ar and th.

This will partly resolve [2] one of frequent complains of Chinese users (as long as they use Chinese Chrome). 
See http://www.google.com/support/forum/p/Chrome/thread?tid=389f306a52817110&hl=en

Leave alone other UI language versions alone for now (Firefox has per-script/per-language min font size [1]). Eventually, there need to be per-script which requires the webkit change.

(note that Firefox does not set these values by default except for Thai, but offers a UI for a user to adjust).

(http://crbug.com/16875)
TEST=Open Chrome with '--lang=zh-CN' and 
  go to http://www.popyard.org/ and Chinese characters are larger than before.

Thank you for the prompt review. 

After some tinkering and experiments, I decided to scale down my changes. 1)
Leave Indian language Chromes alone 2) Set the minimum font size to 12 for
Chinese and 10 for Japanese, Thai, Arabic and Korean to minimize the chance of
disrupting the layout in non-Chinese/Japanese/Korean/Arabic/Thai pages. 

I'll land this 'scaled-down' CL.

Sounds good to me.
